Amidst　the　escalating　impacts　of　global　warming,　the　occurrence　and　severity　of　compound　extreme　weather　events　have　risen　significantly,　presenting　substantial　threats　to　both　lives　and　property.　Existing　response　strategies　predominantly　focus　on　individual　events,　often　overlooking　the　cumulative　effects　rising　from　their　inherent　complexity.　To　address　this　critical　gap,　we　conducted　a　thorough　examination　of　sequential　extreme　precipitation-heatwave　compound　events　(SEPHCE)　in　China　from　1975　to　2020,　utilizing　data　from　1929　meteorological　stations.　Our　investigation　revealed　a　consistent　rise　in　the　frequency　and　duration　of　SEPHCE,　with　a　particularly　notable　surge　since　1993.　Furthermore,　shorter　interval　events　disproportionately　affected　the　regions　of　southwestern　and　southeast　coastal　China.　Furthermore,　SEPHCE　onset　times　exhibited　advancement,　and　the　endings　were　delayed,　thereby　intensifying　the　overall　trend.　These　findings　underscore　the　pressing　need　to　prioritize　effective　planning　and　adaptation　strategies　to　mitigate　the　impact　of　these　compound　event,　while　also　addressing　the　potential　exacerbation　of　inequality　resulting　from　climate　change.
